Heart failure (HF) remains a major cause of morbidity, mortality and healthcare costs, despite available treatments. Psychological issues such as depression, anxiety and poor self-care are prevalent in HF patients. Such issues adversely affect patients’ daily lives and increase hospitalization and mortality rates; therefore, effective approaches to address these are needed. Cognitive-behavioral therapy (CBT) has been proposed as potentially useful for psychological comorbidities in HF patients, but its efficacy is not well-established. This narrative review aimed to summarize the evidence on the effectiveness of CBT for HF patients. A search was conducted using PubMed and Google Scholar for randomized controlled trials (RCTs) on CBT for HF patients. Ten studies (nine RCTs and one case study) were included in the review. CBT was found to be an effective intervention for managing depression, anxiety, low quality of life, and impaired social and physical functioning in HF patients. The results suggest that CBT can improve psychological well-being and enhance the benefits of rehabilitation programs. Face-to-face CBT appears to be superior to conventional therapy and can be implemented in cardiac rehabilitation settings. Further research is needed to evaluate the efficacy of internet-based CBT for cardiac patients and identify factors that promote treatment adherence.
